not be tampered with by irresponsible parties, thus assuring the delivery or"; an accurate quantity of the material to the purchaser.

The, above and other objects of the invention'swill be more fully disclosed in the followingspeci'fication and exemplified inthe accompanying drawings, in which: I

Figure l represents, indiagram, a section through a dispensing apparatus showing the invention applied thereto. j s

Figure 2 is a faceview of the adjustable gauge. I

Figure 3 is a vertical section through the same taken on the line 33 of Figure 2.

Figure 4: is a transverse section through the same taken on the line 44 of Figure 1. 1

Figure 5 is a detail of a modified form of an adjust-able element forming a part of the gauge.

Referring to the accompanying drawings,

and briefly stated, a certain type of dispensing apparatus comprises a tank 7 havinga piston 8 mounted therein, and a rod 9 secured to said piston which projects outwardly through a gland at the top of the tank 7; The top part of the tank is provided with an in let opening 10 and an outlet opening 11 and the bottom part of the tank is provided with an outlet 18 is depressed as shownin Figure 1 the mapasses from a source of supply and is sucked into the top part of the tank through the opening 10, the opening 11 being closed at this time. When it is desired to dispense a given quantity of this material the opening 10 is closed and the fluid under pressure is admitted through opening 11. A

pointer 13 is adjustably secured on the outer of material passing through opening 11. 9

During the sucking in, or filling operation start at zero 28*. properly adjustecl, in orderthat the adjustable part n set the pointer 13 21 which ooenin 12. WVhen the iston of the tank the top part of the tank always.

completely filled with the material at each filling operation and as a certain amount of gas or air resides, withtlie mate'rial'it becomes necessary to recalibrate the gauge when F-Frc. 1

filling the tank 7 with a different weightior density thereof. in the tank therod 9. moves upwardly withthe piston and the materials are dispensed from the tank,.t-he. pointer material due to the gas or air content I After every 'dispensingoperation ranging from the'symbol 1 t IOasindicated at28',;the

regular succession, it will thus benecessary to the zero symbol-28 after each dispensing operation,.and the piston 8 with the pointer 13 may again be elevated todispense the material as hereinbefore described.

As the material becomes ,jcoi'npressed :13 always beings'et to:

'70 rod 9 being elevated after each dispensing operationtoa higher elevationby the piston Sin opposite the. pointer 20 at In order to provide Compensating means to meet the above recited contingency, the

as follows: an -up gauge. 14 is constructed standing plate 15 is secured at its lower'end I in any desired manner to'the tank, as shown;

and is arranged adjacent the. pointer 13 on the rod 9.

The plate 15 is a plurality of screws18 and threadgauge indicator. 1 provided with a flange ing with respect to the the pointers in alignment.

By the above described'arrangement it will beobvious that each provided with a pair ofverf tically disposed slots 16 and 17 which are Mounted to slide in the slots 16 ends of each of said screws is a nut of the plate nut 19 is provided with a pointer rests against the outer edges of the plate 15 in order to prevent them from turn plate and thus keeping;

' 10o nut may be independently adjusted vertically with respect to the plate and may be clamped tightly in such adjusted position theplate being embraced between the heads of the screws at its back andthe nuts at'its face ings.

as clearly shown in the draw- ,In order that the screws 18 may not tampered with after adesired adjustment of the nuts has been made a casing22 is provided said casing being preferably formed of. sheet metal and comprising aback portion 2'8 which covers the heads of screws 18, and the U shaped clips or edge portions 24 which engage with theopposite edges of the plate 15 and proj ectover the face of the plate adjacent said edges.

By this arrangement the casing 22 may he slid onto the plate endwise to any desired position to coverthe heads of screws 18 and locked in such a position by means of the seal or padlock 25 the wire portion of the seal passing through a perforation 26 in the casing and a perforation 27 in the plate 15.

Suitable symbols 28 may be aifixed to the clip face of the casing 22 adjacent the nuts 19indicating a unit of measure or weight as desired.

I r 1 In Figure 5 a -modified'form of gauge indicator is shown, in this construction the pointers-20 are formed on a bar 29 which is designed'to take theplaceof nuts 19 and to be adjustably secured to the plate 15 in a similar manner to that of the nuts.

4 By the above described construction it willbe obvious that, upward pressure may be I exerted on the materialin the tank v7 until said material starts to exude through the opening 11, and thenthe lower nut 19 indicating zero maybe adjusted to synchronize with thepointer 13 and the other nuts may be adjusted asdesired to indicate the required quantity. of material passing through the I opening 11 Having thusdescribed my invention what I claim is: i

1. Ina gauge, a-tplate provided with a slot,

-.a screw passing through said slot with the plate, an indicating pointer nut threaded on said screw and engaging the other side of said plate, a flange on'said pointer nut engaging one edge of said plate in a manner which prevents rotatlon of said polnter nut, a

casing covering the head of said screw, and means for locking said casing to said plate.

3. In a gauge, the combination with an elongated plate provided with a pair of longitudinal slots, and a plurality ofii-ndic'ating nuts each of which has fa pointer overlying the face of said plate and a flange underlying the back of'said plate, said nuts being slide able along said slots; of a casing adapted to slide endwise over said plate nuts, said casing having at each side a' Ushaped portion which embraces said plate andnuts, said casing having aholeextending therethrough which alines with a hole in said plate when the casing is in its operative position, and a seal provided with locking means which eX-' tends through said hole.

In testimony whereof I hereunto affix my signature. 1
